Notes:
Originally Orthoceras referred to all nautiloids with a straight-shell, called an "orthocone," but is now only used to refer to the type species O. regulare of the Baltic states and Sweden. The Peale Museum specimen may have been a similar species in the genus Michelinoceras, more commonly known as the Orthocerida.
The donor may have been John Finney McClenachan (1744-1825), who served in the Chester County (Pa.) militia during the Revolution and later moved to Kentucky.
